图1是本申请第一实施例中的有机发光二极管(Organic Light-Emitting Diode,OLED)阵列基板的俯视图；图2是沿着图1中的AA直线的剖视图。
参照图1与图2所示，该OLED阵列基板1包括显示区10和显示驱动芯片12，显示区10包括非透明显示区10a与透明显示区10b；显示驱动芯片12包括多个数据信号通道。
其中，非透明显示区10a包括阵列式排布的第一OLED像素11，第一OLED像素自下而上包括：块状第一电极、OLED发光结构以及第二电极。各列第一OLED像素11对应显示驱动芯片12的至少一个数据信号通道。在本申请实施例中，各列第一OLED像素11对应显示驱动芯片12的多个数据信号通道。
在本实施例中，透明显示区10b包括一行多列的第二OLED像素13。各列第二OLED像素13包括：沿列方向延伸的第一电极、位于第一电极上多个彼此分隔的OLED发光结构以及位于多个发光结构上的第二电极。各列第二OLED像素13被驱动时，透明显示区10b具有显示功能；各列第二OLED像素13未被驱动时，透明显示区10b具有透光功能。各列第二OLED像素13对应同一显示驱动芯片12的至少一个数据信号通道。各列第一OLED像素11与各列第二OLED像素13对应多个数据信号通道，通过多个数据信号通道输出的数据对应显示区10的一帧画面。
参照图2所示，第二OLED像素13自下而上包括：沿列方向延伸的第一电极131、OLED发光结构133以及第二电极132。多个OLED发光结构133由像素定义层14隔开。第一OLED像素11中自下而上的结构与第二OLED像素13的结构相同。其它可选方案中，OLED发光结构133之间也可以无像素定义层。
第二OLED像素13与第一OLED像素11的区别在于：每列第二OLED像素13中，第一电极131与OLED发光结构133贯穿透明显示区10b，例如自透明显示区10b的顶端延伸至底端。每列第二OLED像素13中的第二电极132可以贯穿透明显示区10b，例如自透明显示区10b的顶端延伸至底端。在一示例中，如图2所示，各列第二OLED像素13的第二电极132连成一面电极。在另一示例中，各个第一OLED像素的第二电极与各个第二OLED像素的第二电极连接成一面电极。
图1与图2中，透明显示区10b的所有列第二OLED像素13为同色像素。可选方案中，透明显示区10b的所有列第二OLED像素13可以为红色像素、绿色像素、蓝色像素、黄色像素等中的任一种像素。换言之，透明显示区10b执行显示功能时，该区域为单色发光。
在一行所有列或两行所有列的第二OLED像素为同色像素的情况下：在一可选方案中，一行第二OLED像素中各列同色像素的第一电极连接至同一像素驱动电路中的驱动晶体管的漏极，该驱动晶体管的栅极对应显示驱动芯片的一个数据信号通道，该驱动晶体管的源极连接一电源电压。另一可选方案中，一行各列同色像素中，每个像素的第一电极可以连接至一个像素驱动电路中的驱动晶体管的漏极，每一驱动晶体管的栅极对应显示驱动芯片的一个数据信号通道，每一驱动晶体管的源极连接同一或不同电源电压。相对于后者方案，前者像素驱动电路中的驱动晶体管数目少、所占面积少；另外，对数据信号通道的数目要求少，连接走线数目也少、占用面积少。
在一列所有行或两列所有行第二OLED像素为同色像素的情况下：在一可选方案中，一列所有行同色像素的第一电极连接至同一像素驱动电路中的驱动晶体管的漏极，该驱动晶体管的栅极对应显示驱动芯片的同一数据信号通道，该驱动晶体管的源极连接同一电源电压。其它可选方案中，也可以两列所有行同色像素的第一电极连接至同一像素驱动电路中的驱动晶体管的漏极，该驱动晶体管的栅极对应显示驱动芯片的同一数据信号通道，该驱动晶体管的源极对应同一电源电压。
对于上述两种情况下的方案，透明显示区执行显示功能时，该透明显示区为单色发光，例如发红光、蓝光、绿光等。
其它可选方案中，第二OLED像素13中的第一电极131、OLED发光结构133也可以与第一OLED像素11完全相同，都设置为阵列式。在本申请实施例的透明显示区10b 中，第二OLED像素13的第一电极131、OLED发光结构133设置为贯穿透明显示区10b(例如自透明显示区10b的顶端延伸至底端)的若干列，相对于阵列式分布的若干行列单元，可以减少图形膜层的交界，改善透光时的衍射问题。
，在一个可选方案中，一组至少一列的第二OLED像素按照以下任一种方式排布：一行多列；多行多列。多行多列包括两行多列的情形，当为两行多列时，一列中的两行第二OLED像素的颜色相同。
以下介绍透明显示区10b的各列第二OLED像素13的发光驱动方式。
主动驱动式OLED(Active Matrix OLED，AMOLED)，也称有源驱动式中，包括薄膜晶体管(Thin Film Transistor，TFT)阵列，每一薄膜晶体管单元包含存储电容。AMOLED是采用独立的薄膜电晶体管控制每个像素发光，且每个像素可以连续发光。换言之，每个第二OLED像素13的寻址直接受控于薄膜晶体管阵列。薄膜电晶体管阵列的行选择信号可以来源于GIP(Gate-drive-Ic(integrated circuit)-in Panel)电路、列选择信号可以来源于显示驱动集成芯片(DDIC，Display Driver Ic Chip)。显示驱动集成芯片在上下文中被简称为显示驱动芯片或DDIC。
图3是透明显示区各列第二OLED像素的一种主动驱动式的电路示意图。参照图3所示，各列第二OLED像素13的第一电极连接至像素驱动电路中的同一驱动晶体管的漏极，第二电极接地；该驱动晶体管的栅极对应显示驱动芯片的同一数据信号通道。图3中，像素驱动电路包括一开关晶体管X1、一驱动晶体管X2以及一存储电容C。该数据线可以接入DDIC的一个数据信号通道(即source线)；扫描线可以接入GIP电路的一个扫描信号通道。显示驱动芯片的其余数据通道可以提供给非透明显示区10a的各列第一OLED像素11，即每列第一OLED像素11占据一个数据信号通道。GIP电路的其余扫描信号通道可以提供给非透明显示区10a的各行第一OLED像素11，即每行第一OLED像素11占据一个扫描信号通道。利用数据信号通道中的R/G/B数据信号控制驱动晶体管X2的栅极，从而实现控制电源电压VDD流向透明显示区10b每一列第一电极的电流大小。
一个可选方案中，显示驱动芯片的其余数据信号通道可以提供给非透明显示区10a的各列第一OLED像素11；每列第一OLED像素11占据一个数据信号通道。
另一个可选方案中，各列第二OLED像素13占用显示驱动芯片的一个数据信号通道可以与非透明显示区10a的一列第一OLED像素11共用；每列第一OLED像素11占据一个数据信号通道。换言之，显示驱动芯片中存在一个同时提供给一列第一OLED像素11与多列第二OLED像素13的数据信号通道。此外，每列第一OLED像素11占据一个数据信号通道。
在上述两个可选方案中，后一种方案对显示驱动芯片的数据信号通道数目要求少。
对于数据信号通道共用的情况，非透明显示区10a各列第一OLED像素11对应的多个数据信号通道的数据对应显示区10的一帧画面。对于数据信号通道不共用的情况，非透明显示区10a各列第一OLED像素11与透明显示区10b各列第二OLED像素13总共对应的数据信号通道的数据对应显示面板的一帧画面。对应显示区10的一帧画面是指：在一个图像刷新周期内，各数据通道的数据由对一副图像处理得来。

参照图4中的GIP电路驱动的波形图，第一栅极线Vgh为高电平，第二栅极线Vgl为低电平，第一时钟信号线XCK和第二时钟信号线CK分别输出高低电平相反的数字信号。在第一时钟信号线XCK跳变为低电平时，第1级GIP电路输入信号线G1级输入一低电平，在第二时钟信号线CK跳变为低电平时，第1级GIP电路输出低电平，作为第2级GIP电路的输入信号G2，并以此类推，第n级电路的输出信号作为第n+1级电路的输入信号。
在具体实施过程中，上述像素驱动电路中的电源电压VDD优选可调，以改变透明显示区10b的第二OLED像素13的发光亮度，使其接近非透明显示区10a的第一OLED像素11的发光亮度。
一个可选方案中，第二OLED像素13对应的像素驱动电路中的电源电压VDD可以共用给第一OLED像素11对应的像素驱动电路。上述电源电压VDD可以来源于显示驱动芯片，也可以来源于电源芯片。
另一个可选方案中，第二OLED像素13对应的像素驱动电路中的电源电压VDD与第一OLED像素11对应的像素驱动电路中的电源电压不共用。上述第二OLED像素13对应的电源电压VDD可以来源于电源芯片。

一个可选方案中，除上述第二OLED像素13中各晶体管单元占据的多个数据信号通道之外，显示驱动芯片的其余数据信号通道可以提供给非透明显示区10a的各列第一OLED像素11。另一个可选方案中，一列第二OLED像素13占用显示驱动芯片的数据信号通道可以共用给非透明显示区10a的一列第一OLED像素11，换言之，显示驱动芯片的各个数据信号通道中，存在至少一个这样的数据信号通道，至少一个这样的数据信号通道同时提供给一列第一OLED像素11与一列第二OLED像素13。此外，每列第一OLED像素11占据一个数据信号通道。
对于数据信号通道充分共用的情况，非透明显示区10a各列第一OLED像素11对应的数据信号通道的数据对应显示区10的一帧画面。对于数据信号通道不共用的情况，非透明显示区10a各列第一OLED像素11与透明显示区10b各列第二OLED像素13总共对应的数据信号通道的数据对应显示区10的一帧画面。
一个可选方案中，除上述各晶体管单元占据的一个扫描信号通道之外，GIP电路的 其余扫描信号通道可以提供给非透明显示区10a的各行第一OLED像素11。另一个可选方案中，透明显示区10b的各列第二OLED像素13与非透明显示区10a的一行第一OLED像素11共用一个扫描信号通道。
图6是具有对驱动晶体管的阈值电压进行补偿功能的一种像素驱动电路的电路图以及时序图。在具体实施过程中，像素驱动电路除了上述的2T1C，即2个薄膜晶体管和一个电容器，还可以为7T1C、6T1C等对驱动晶体管的阈值电压进行补偿的像素驱动电路。图6所示为7T1C像素驱动电路，该电路分为三个工作阶段：复位、补偿、发光。工作原理为：在补偿阶段把驱动晶体管的阈值电压Vth先存储在它的栅源电压Vgs内，在最后发光阶段，把电压Vgs-Vth转换为电流，因为Vgs已经包含了Vth，因而在转化成电流时就把Vth的影响抵消了，从而实现了电流的一致性。上述电路可以提高第二OLED像素13的寿命以及显示均匀性。
针对各列第二OLED像素13对应的第一电极连接至像素驱动电路中的同一驱动晶体管的漏极，该驱动晶体管的栅极对应显示驱动芯片的一个数据信号通道，源极连接一电源电压的情况：上述像素驱动电路的数据线信号VDATA可以来自显示驱动芯片的一个数据信号；扫描线Gn-1、Gn的信号可以来自GIP电路的两行扫描信号，发射信号EM可以来自GIP电路的一行发射信号，初始信号INIT可以来自显示驱动芯片。

上述设置方式的各列第二OLED像素13'可以具有相同颜色，即透明显示区10b单色显示；也可以具有不同颜色，即透明显示区10b彩色显示。
图11是本申请第四实施例中的OLED阵列基板的俯视图。参照图11所示，本实施例中的OLED阵列基板4与前述实施例中的OLED阵列基板1、2、3大致相同，区别仅在于：某一列、某几列或所有列的第二OLED像素13"在列方向上呈葫芦状。换言之，某一列、某几列或所有列的第二OLED像素13"对应的第一电极、OLED发光结构在列方向上呈葫芦状。上述结构相对于直角矩形、圆角矩形能进一步降低透光时的衍射现象。
上述形状的各列第二OLED像素13"可以为同色的像素，即透明显示区10b单色显示；也可以为不同颜色的像素，即透明显示区10b彩色显示。
图12是本申请第五实施例中的OLED阵列基板的俯视图。参照图12所示，本实施例中的OLED阵列基板5与前述实施例中的OLED阵列基板1结构大致相同，区别仅在于：第二OLED像素13为两行多列。
两行多列第二OLED像素13的结构可以参照前述实施例一至四中的结构。
图13是透明显示区两行各列第二OLED像素的一种主动驱动式的电路示意图。与图3相比，第一行各列同色像素对应的第一电极连接至第一像素驱动电路中的第一驱动晶体管的漏极，第一驱动晶体管的栅极对应显示驱动芯片的第一数据信号通道，第一驱动晶体管的源极连接第一电源电压；第二行各列同色像素对应的第一电极连接至第二像素驱动电路中的第二驱动晶体管的漏极，第二驱动晶体管的栅极对应显示驱动芯片的第二数据信号通道，第二驱动晶体管的源极连接第二电源电压。此外，第一行各列同色像素与第二行各列同色像素对应同一扫描信号。这样，透明显示区的第二OLED像素为同时打开。

参照图13与图14的同色像素驱动方式，本实施例中的两行第二OLED像素13的驱动相当于前一实施例中的两个一行第二OLED像素13的驱动。区别在于：上下两行的像素在驱动时，可以共用数据信号。
在两行多列第二OLED像素为多个颜色的像素的情况下，一列中上下两行的像素的颜色优选相同，此时两行的像素可以分别对应一数据信号，也可以共用一列数据信号。此外，第一行各列同色像素与第二行各列同色像素对应同一扫描信号。换言之，透明显示区的第二OLED像素13同时打开。
在本申请实施例中，“行”和“列”属于相对概念。在对OLED阵列基板的布置过程中，因面对OLED阵列基板的位置和/或角度发生变化而导致“行”和“列”的相对位置发生变化是可能的。根据上述实施例的“一行多列”第二OLED像素的设置是能够直接得出或推断出“多行一列”的第二OLED像素的设置情形。此外，本领域技术人员还可以基于本申请实施例在实际应用中调整行/列的第二OLED像素的数量，例如根据上述实施例的“一行多列”第二OLED像素的设置调整成“多行多列”第二OLED像素的设置、“一行一列”第二OLED像素的设置。在下面实施例中以“多行一列”第二OLED像素和一行一列”第二OLED像素为例做详细说明。
图15是本申请第六实施例中的OLED阵列基板的俯视图。参照图15所示，本实施例中的OLED阵列基板6包括显示区10和显示驱动芯片12，显示区10包括非透明显示区10a与透明显示区10b；显示驱动芯片12包括多个数据信号通道。
其中，非透明显示区10a包括阵列式排布的第一OLED像素11，第一OLED像素自下而上包括：块状第一电极、OLED发光结构以及第二电极。各列第一OLED像素11对应显示驱动芯片12的至少一个数据信号通道。
在本实施例中，透明显示区10b包括两列多行的第二OLED像素13。各列第二OLED像素13包括：沿行方向延伸的第一电极、位于第一电极上多个彼此分隔的OLED发光结构以及位于多个发光结构上的第二电极。两列多行的第二OLED像素被驱动时，透明显示区10b具有显示功能；两列各行第二OLED像素未被驱动时，透明显示区10b具有透光功能。两列各行第二OLED像素对应同一显示驱动芯片的至少一个数据信号通道。各行第一OLED像素11与各行第二OLED像素13对应的多个数据信号通道，通过多个数据信号通道输出的数据对应显示区10的一帧画面。
与前述实施例五中的OLED阵列基板5相比，区别在于：第二OLED像素13呈两列多行分布。
每一个第二OLED像素13对应的第一电极沿行方向延伸。
图16是透明显示区两列多行第二OLED像素的一种主动驱动式的电路示意图。参照图16所示，同一列的行同色像素对应的第一电极连接至同一像素驱动电路中的驱动晶体管的漏极，该驱动晶体管的栅极对应显示驱动芯片的同一数据信号通道，该驱动晶体管的源极连接一电源电压。换言之，该透明显示区占据了两个数据信号通道。
其它可选方案中，一列各行同色像素对应的第一电极连接至一个像素驱动电路 中的驱动晶体管的漏极，每一驱动晶体管的栅极对应显示驱动芯片的一个数据信号通道，每一驱动晶体管的源极连接一电源电压；也可以两列所有行同色像素对应的第一电极连接至同一像素驱动电路中的驱动晶体管的漏极，该驱动晶体管的栅极对应显示驱动芯片的同一数据信号通道，该驱动晶体管的源极连接一电源电压。
此外，一列第二OLED像素中，一行或多行第二OLED像素也可以与一行第一OLED像素共用显示驱动芯片的同一数据信号通道。
在一可选方案中，第二OLED像素设置为一列若干行、两列若干行的形式，能够减少图形膜层的交界，改善透光时的衍射问题，因而透明显示区下的光传感器成像效果佳。
图16中的像素驱动电路以2T1C为例，其它可选方案中，也可以为3T1C、6T1C、7T1C等像素驱动电路。
图17是透明显示区两列多行第二OLED像素的一种主动驱动式的电路示意图。参照图17所示，在一列第二OLED像素中，各像素单元(其由三行两列的子像素形成)的各行同色子像素对应的第一电极连接至同一像素驱动电路中的驱动晶体管的漏极，每一驱动晶体管的栅极对应显示驱动芯片的一个数据信号通道。在一可选方案中，在一列第二OLED像素中，各像素单元的各行同色子像素对应的第一电极连接至不同像素驱动电路中的驱动晶体管的漏极，每一驱动晶体管的栅极对应显示驱动芯片的一个数据信号通道，每一驱动晶体管的源极连接一电源电压。在另一可选方案中，在两列第二OLED像素中，各像素单元的各行同色子像素对应的第一电极连接至同一像素驱动电路中的驱动晶体管的漏极，每一驱动晶体管的栅极对应显示驱动芯片的一个数据信号通道，每一驱动晶体管的源极连接一电源电压。
通过上述方式，与非透明显示区的像素单元相比，透明显示区的像素单元可以看成一列若干行、两列若干行的像素单元，如此，透明显示区执行显示功能时，各个像素单元内的各个子像素发光，显示效果与非透明显示区的显示效果更接近。
图17中的像素驱动电路以2T1C为例，其它可选方案中，也可以为3T1C、6T1C、7T1C等像素驱动电路。
图18是本申请第七实施例中的OLED阵列基板的俯视图。参照图18所示，本实施例中的OLED阵列基板7与图15中的OLED阵列基板6的区别在于，省略一列的第二OLED像素，同时将另一列的第二OLED像素沿行方向延伸。对应地，本实施例的第二OLED像素的结构请参照图15中的第二OLED像素的结构；本实施例的像素驱动电路，省略上述图16至17中的一套像素驱动电路即可。
本申请实施例还提供一种在上述的OLED阵列基板上设置有封装层的显示面板。显示面板除了作为显示器件使用外，还可以在其上设置触控层，作为触控面板用。显示面板也可以作为半成品与其它部件集成、装配在一起形成如手机、平板电脑、车载显示屏等的显示装置。
显示装置中，显示面板的透明显示区10b的下方对应设置光传感器，光传感器包括：摄像头、虹膜识别传感器以及指纹识别传感器中的一种或组合。
虽然本申请披露如上，但本申请并非限定于此。任何本领域技术人员，在不脱离本申请的精神和范围内，均可作各种更动与修改，因此本申请的保护范围应当以权利要求所限定的范围为准。
